Hi all,
I've been having some problems with kmail crashing when changing folders. I've
applied the patch from
https://bugs.kde.org/show_bug.cgi?id=174065
to gt4-gui, which seems to have solved the problem. Given that the patch
applies cleanly to the FreeBSD qt4-gui port (4.4.3_1), might I suggest adding
it to the repository? I've attached it for ease of reference.
Kind regards,
Jaap Boender
